Echinodermata: “ Spiny Skinned”Sea Stars, Sea Lillies, Sea Urchins p.22

Phylum EchinodermataSymmetry

Adults have pentaradial symmetry Larvae are bilaterally symmetrical

Internal skeleton made of calcium plates

Special Fluid filled System (water vascular system)

Phylum EchinodermataEndoskeleton : calcium-rich endoskeleton

composed of plates called ossiclesFive-Part Radial Symmetry : larvae are

bilateral, as grow into adults, develop pentaradial symmetry

Phylum EchinodermataWater-vascular System : a water filled

system of interconnected canals of tiny hollow tube feet.Tube Feet act as tiny legs used to move, grip

and manipulateWalls of tube feet also used for gas exchange

and waste excretion

Phylum EchinodermataCirculation & Respiration: Body cavity, or

coelom, functions as a simple circulatory and respiratory system

The Shape of life: “Ultimate Animals”What are the common names of 4 major echinoderms?How do sea stars walk and grab?What is the term that describes how an animal grows new

replacement for lost body parts?How are cnidarians and echinoderms similar?How do sea stars feed on mussels?What two structures are scattered between the spines of sea

stars?How can you investigate animals that don’t seem to move?How does a water-vascular system work?How can a sea star be flexible and then suddenly become rigid as

a rock?Advantages and disadvantages of extrusible stomach?What are the benefits of being headless and not bilateral?

Warm-up 04/29List the EightPhyla we have covered and one

UNIQUE characteristic of each.Porifera- filter feeders, asymmetrical, specialized

cellsCnidaria- stinging cells, radial symmetry, first to

movePlatyhelminthes- move with intent, bilateral

symmetry, first hunters, hermaphroditesNematoda- one way digestion, separate sexesAnnelida- first circulatory system, bilateral, first

central nervous systemMollusca- first visceral mass, foot, mantle, Arthropoda- segmented legs and body, exoskeleton Echinodermata- pentaradial, only found in ocean
